Victory / Outcome
The United States, with the help of the United Kingdom and Canada designed and bulit the first atomic bombs under the secret name, "The Manhattan Project". The US eventually droped the bomb entitled "Fat Man", made mostly of plutonium-239, on Nagasaki on August 9, 1945 by direct orders from US President Harry S. Truman. These are to date the only attacks with nuclear weapons in the history of warfare. This bombing, along with the bombing of Hiroshima, ultimately led to the end of World War II.

Purpose
The criteria for the targeted cities of Japan are as follows:
  • They are larger than three miles in diameter and are important targets in a large urban area.
  • The blast would create effective damage.
  • They are unlikely to be attacked by August 1945. "Any small and strictly military objective should be located in a much larger area subject to blast damage in order to avoid undue risks of the weapon being lost due to bad placing of the bomb."
The goal of the bombs were to convince Japan to surrender unconditionally in accordance to the terms with the Potsdam Declaration.

Importance
Six days after the bombing of Nagasaki (August 15th), Japan announced its surrender to the Allied Powers. On September 2nd, Japan signed the Instrument of Surrender that officially ended the Pacific War and therefore World War II. The bombing even led, in part, to post-war Japan adopting Three Non-Nuclear Principles, forbidding the nation from nuclear armament.

The energy released by the bomb was powerful enough to burn through clothing. The dark portions of the garments this victim wore at the time of the blast were emblazoned on to the flesh as scars, while skin underneath the lighter parts (which absorb less energy) was not damaged as badly.

The bombs killed as many as 140,000 people in Hiroshima and 80,000 in Nagasaki by the end of 1945, roughly half on the days of the bombings. Amongst these, 15% to 20% died from injuries or illness attributed to radiation poisoning. Since then, more have died from leukemia (about 231) and cancers (334) attributed to exposure to radiation released by the bombs. In both Hiroshima and Nagasaki, the overwhelming majority of the dead were civilians.
